420440 Scania PULLEY

A pulley is pretty simple, actually. It’s basically a wheel with a grooved rim, and its job is to guide a belt – usually the serpentine belt or a V – belt – around an engine component. It allows the belt to transfer rotational power efficiently. Different pulleys do different things – some drive the alternator to make electricity, others run the power steering pump, the AC compressor, or even the water pump. They all spin, and they all rely on that belt staying in the groove. Think of it as a key link in a chain. The engine is making power, and the belt, guided by the pulleys, takes that power to all those important accessories I mentioned. It’s not making the power itself, it’s just directing it where it needs to go. Without a functioning pulley, that accessory won’t run properly, or at all. You’ll notice if a pulley is failing because the accessory it powers will start acting up – like weak power steering, a failing AC, or even your battery light coming on if it’s related to the alternator. A failing pulley can cause a bunch of problems. If it seizes up, it puts a huge strain on the belt – and sometimes even the engine. A cracked or damaged pulley can cause the belt to slip or break, leaving you stranded. It’s a relatively inexpensive part, but it acts like a shield for a lot of more expensive components. Keeping it in good shape prevents bigger headaches down the road. We carry a good selection of pulleys at Fixparts Online, and honestly, replacing a pulley is often something a reasonably handy person can do themselves. Adaptable to any vehicle: Pulley (MPN 0420440) comes with a 12-month warranty!
